This heavy duty MP5 includes a full RAS rail system. It also includes a 30mm optic mount for popular red dot optics. The battery is stored inside of the vertical foregrip, which is shaped similar to an M4 style pistol grip for comfort. It also features a retractable stock to adjust to your needs.

What is JG or GB or Echo1? JG stands for Jing Gong, which is actually Chinese for Golden Bow; hence GB. Also, GB or JG manufactures for Echo 1, they are OEM Jing Gong airsoft AEG guns. All these different names for the same airsoft manufacturer is confusing. Hopefully, this has helped clairfy the confusion.

While waiting for the MPEG to arrive, I checked into the gun. I had my
doubts from what I heard from different people, but they were blown
away when I received it. When UPS arrived at my front door, I was
excited to see what AirSplat sent me. The packaging inside the box
was great, and nothing was damaged at all. My first impression of
the MP5-SD6’s (Yes, I know it says “M5-S6” on the box, but it’s really
modeled after the MP5-SD) box was, “Wow!” For $79.99, I was
impressed. The box was very durable and was not falling apart – a
good sign that nothing will be broken before you even use the gun.
Now as you can see in the picture above and below, the box doesn’t
have any fancy designs on or in it, but that doesn’t matter to me.
What matters to me is what is actually inside and how well it is
packaged.

So I opened up the box and was again impressed. Everything was
tightly packed and secured – a good sign. I then began looking at
everything that was included. There was the actual MP5-SD6 itself, a
battery and charger (nice for newer players), the magazine, the BB
loader, and the cleaning rod along with the manual and small bag of
.2 BBs. Again, for $79.99, (Although free for us thanks to AirSplat),
you get the complete package. There is no need to worry about
buying a charger and battery, which I think is great for newcomers of
the sport.

Look and Feel:

The overall look of the MP5-SD6 is very good. It has a nice black
finish to it. The silencer is painted orange at the end, of course due to
federal laws. The magazine is metal (a plus!) with a good part of the
gun being metal as well. Most of the external body is plastic which
may cause some of you to wince at, but it is a MPEG. The handgrip is
excellent; it has a nice feel to it, and the design is great as well. The
silencer can be unscrewed to reveal the barrel - again metal. The
retractable stock is plastic, but has a comfortable feel to it. It has two
modes: all the way inward and all the way extended. Most people
prefer the extended, which is also my preference. Ther
